本公开的较佳实施方式
下面结合附图对本公开的实施方式进行描述。
本公开实施例提供一种利用射频能量采集技术以提高终端电池续航能力的方法、装置及终端。
随着智能终端和可穿戴设备的普及，有限的电池容量限制了这些设备的继续发展。与此同时，能量采集技术得到了迅速发展，并在无线传感网络、物联网等领域具有广泛的应用。以自由空间中的射频信号为能量来源的射频能量采集技术，可以将自由空间中的电磁能量转化为电能，从而驱动低功耗电子设备或者作为辅助手段延长电子设备的工作时间。而智能终端尤其是智能手机无时无刻不在发射射频信号，自由空间中也蕴含着异常丰富的射频信号。如果能将这种广泛存在的微能量，通过将射频能量采集技术和终端电池 结合在一起，便可以提高手机的续航能力，延长手机的使用时间。
实施例一
如图1所示，该图给出了本公开实施例提供的一种提高终端电池续航能力的方法，从图中可以看出，该方法可以包括：
S110、根据终端的当前通信连接状态从所述终端的所有天线中确定候选天线；
可以理解地，所述终端的通信连接状态可以是通话状态、移动数据连接状态、无线保真(Wi-Fi，Wireless-Fidelity)连接状态、蓝牙连接状态或全球定位系统(GPS，Global Positioning System)连接状态，也可以是非通信连接状态，也就是终端没有进行任何通信连接。终端可以通过内置的天线实现上述通信连接状态。例如，通过内置的第二代移动通信技术(2G，The 2nd Generation)/第三代移动通信技术(3G，The Third Generation)/第四代移动通信技术(4G，The 4th Generation)等主天线分别对应实现通话状态、3G移动数据连接状态和4G移动数据连接状态，另外，终端还可以通过内置的分集天线来辅助4G射频信号的接收。相应地，终端可以通过内置的Wi-Fi/蓝牙天线/GPS，三合一天线分别实现Wi-Fi连接状态、蓝牙连接状态和GPS连接状态。
S120、根据所述候选天线当前各自接收的射频信号强度从所述候选天线中选出用于采集射频信号的采集天线；
这里，可选地，可以确定所述候选天线各自接收的射频信号强度是否超出预设的强度阈值，并将接收的射频信号强度超出所述强度阈值的候选天线用于采集射频信号。
可以理解地，将接收的射频信号强度超出预设的强度阈值的候选天线用于采集射频信号，可以达到选择射频信号强度较大的接收天线来进行射频信号的采集，从而提高射频信号的采集效率，加快电池的充电速度。
另外，可以说明的是，终端可以使用内置的天线(如用于接收和发送2G/3G/4G等信号的主天线、用于辅助接收4G信号的分集天线和Wi-Fi/蓝牙/GPS三合一天线)来进行射频信号的采集，即射频信号的捕获，还可以使用 外加天线或天线阵列来实现射频信号的采集。相比于终端内置的天线，外加天线频带更宽，增益更大，因此射频信号的采集效率也会更高。此外，通过选用不同性能的天线，还可以实现对特定频段的射频信号的采集。用于采集射频信号的采集天线可以是一种，也可以是两种或者两种以上，此处对于采集天线的数目不做限制。
S130、通过所述采集天线捕获所述终端周围环境中的射频信号；
可以理解地，不同类型的天线可以对应捕获(即接收)不同频段的射频信号。例如，终端内置的2G天线能够接收的信号频段为900MHz/1800MHz，应用于全球移动通信系统(GSM，Global System for Mobile Communication)；或能够接收信号频段为800MHz的2G天线，应用于码分多址系统(CDMA，Code Division Multiple Access)；3G天线能够接收的信号频段为2100MHz，应用于CDMA2000系统或宽带码分多址系统(WCDMA，Wideband Code Division Multiple Access)，或能够接收信号频段为1880-1920MHz的3G天线，应用于时分同步码分多址系统(TD-SCDMA，Time Division-Synchronous Code Division Multiple Access)，Wi-Fi天线可接收信号频段为2.4GHz；对于每种类型的天线可以接收的信号频段在相关的标准中都有相应的规定，因此此处不再赘述。
S140、将所述射频信号按照预设的转换规则转换成稳定的直流信号；
可以理解地，射频信号是一种高频交流变化电磁波的简称，也就是说，射频信号包含的射频能量是一种高频交流电能，而终端电池充电所需的能量是稳定的直流电能，因此，这里是先将接收的射频信号按照预设的转换规则转换成稳定的直流信号，才能够对终端电池进行充电。
S150、利用所述稳定的直流信号对所述终端的电池进行充电。
这里，所述终端内可以只有一块电池，也可以包括主电池和备用电池。当终端包括主电池和备用电池时，对于步骤S150，所述利用所述稳定的直流信号对所述终端的电池进行充电，可以包括如下步骤：
S1501、根据所述终端的主电池和备用电池的电量状态确定目标电池；
可选地，当所述终端的主电池和备用电池的电量同时达到预设的充电阈 值时，将所述终端的主电池确定为目标电池；当所述终端的主电池和备用电池中只有一个电池的电量达到预设的充电阈值时，将达到所述充电阈值的电池确定为目标电池。这样做可以保证终端的主电池一直都有足够的电量。
S1502、利用所述稳定的直流信号对所述目标电池进行充电。
示例性地，对于步骤S110，所述根据终端当前的通信连接状态从所述终端的所有天线中确定候选天线，如图2所示，可以包括如下步骤：
S1101、实时获取所述终端的电池电量；
S1102、当所述终端的电池电量达到预设的充电阈值时，获取所述终端的当前通信连接状态；
S1103、在所述终端的所有天线中确定用于维持所述当前通信连接状态的工作天线；
S1104、将所述终端的所有天线中除去所述工作天线以外的其他天线确定为候选天线。
这里，通常情况下，用于采集射频信号的采集天线可以不包括维持终端当前通信连接状态的工作天线，从而可以避免射频能量采集(即射频信号采集)给终端当前通信连接状态带来的负面影响，确保终端的正常通信。例如，终端内置的天线包括：用于接收和发送2G/3G/4G等信号的主天线、用于辅助接收4G信号的分集天线和Wi-Fi/蓝牙/GPS三合一天线。例如，此时终端处于通话状态，如图3所示，从图中可以看出，此时正在工作的天线为2G天线，则终端可以将其内置的所有天线中除去2G天线以外的其他天线确定为候选天线，即将图3(a)所示的阴影部分的天线确定为候选天线；可选地，终端可以将接收的射频信号强度超出所述强度阈值的候选天线用于采集射频信号，例如图3(b)所示的4G主天线、用于辅助接收4G信号的分集天线和Wi-Fi天线。如果此时终端处于非通信连接状态，则终端可以将其内置的所有天线确定为候选天线。
示例性地，对于步骤S140，所述将所述射频信号按照预设的转换规则转换成稳定的直流信号，可以包括：
S1401、通过预设的整流电路将所述射频信号转换成直流信号；
可以说明的是，在实际的工程应用中，在所述射频信号经过整流电路之前，所述射频信号还可以经过匹配电路，从而可以避免接收的射频信号出现信号反射的现象，保证整流电路的较大能量转换效率。
S1402、通过预设的稳压电路将所述直流信号的电压值保持在预设的电压范围内，获得稳定的直流信号。
这里，以正弦波表示射频信号对上述射频信号转换为稳定的直流信号的过程进行说明，如图4所示，该图给出了射频信号S1经匹配电路、整流电路和稳压电路，并最终输出稳定的直流信号S4的过程。从图中可以看出，信号S2是输入信号S1通过匹配电路输出的信号流，信号S3是输入信号S2通过整流电路输出的信号流，信号S4是输入信号S3通过稳压电路输出的信号流。
可以理解地，终端电池的充电过程是一个恒流充电和恒压充电的过程，也就是说，只有恒定的电流或者电压才能够为终端电池进行充电。但是，由于整流电路转换的直流信号的电压值并不是恒定的电压值，因此在对终端电池进行充电之前，还可以将转换后的直流信号通过预设的稳压电路转换成稳定的直流信号，从而使得转换后的直流信号的电压值保持在预设的电压范围内，实现对终端电池的持续充电。
本公开实施例提供了一种提高终端电池续航能力的方法，该方法能够在不影响终端正常通信的前提下，利用终端内置的多个天线来实现自由空间广泛存在的射频信号的采集，并将其所采集的射频信号转化成稳定的直流信号，从而实现终端电池的持续供电；另外，该方法还可以根据接收的射频信号的强弱选择用于采集射频信号的采集天线，从而大大提高了射频信号采集的效率，加快了终端电池的充电速度。
实施例二
为了方便对上述技术方案的理解，在实施例二中以终端电池包括主电池和备用电池为例，对本公开实施例提供的一种提高终端电池续航能力的实施过程进行详细地描述，参见图5，从图中可以看出，该实施过程可以包括如下步骤：
S301、实时获取所述终端的主电池和备用电池的电量；
S302、当所述主电池和备用电池中的任一电池的电量达到预设的充电阈值时，确定目标电池，并获取所述终端的当前连接状态；
这里，对于确定目标电池，可以包括两种情况：当所述终端的主电池和备用电池的电量同时达到预设的充电阈值时，将所述终端的主电池确定为目标电池；当所述终端的主电池和备用电池中只有一个电池的电量达到预设的充电阈值时，将达到所述充电阈值的电池确定为目标电池。这样做可以保证终端的主电池一直都有足够的电量。
S303、在所述终端的所有天线中确定用于维持所述当前通信连接状态的工作天线；
S304、将所述终端的所有天线中除去所述工作天线以外的其他天线确定为候选天线；
S305、获取所述候选天线当前各自接收的射频信号强度，并将接收的射频信号强度超出预设的强度阈值的候选天线确定为用于采集射频信号的采集天线；
S306、通过所述采集天线捕获所述终端周围环境中的射频信号；
S307、通过预设的整流电路将所述射频信号转换成直流信号；
这里，可以说明的是，在实际的工程应用中，在所述射频信号经过整流电路之前，所述射频信号还可以经过匹配电路，从而可以避免接收的射频信号出现信号反射的现象，保证整流电路的较大能量转换效率。
S308、通过预设的稳压电路将所述直流信号的电压值保持在预设的电压范围内，获得稳定的直流信号；
S309、利用所述稳定的直流信号对所述目标电池进行充电。
由上述实施过程可以看出，本公开实施例提供的一种提高终端电池续航能力的方法能够通过选择合适的采集天线来采集周围环境中较为丰富的射频信号，从而在不影响终端正常通信的前提下，能够大大提高射频信号的采集效率，加快终端电池的充电速度。
